摘　　要：采用常规压片法对二色补血草(Limonium bicolor)、杂种补血草(Limonium latifolium)、深波叶补血草(Limonium sinuatum)的染色体数目及核型进行了研究。结果表明:3种补血草属植物均为二倍体,染色体数目分别为2n=16、18、16;核型类型分别为2B、1B、2B型;核型公式分别为2n=2x=16=14m+2sm、2n=2x=18=18m、2n=2x=16=12m+4sm;核型不对称系数分别为56.12%,56.72%,58.47%。The chromosome number and karyotype of three species of Limonium（L. bicolor,L. latifolium,L, sinuatum）were studied by squash method. The results showed that they were diploid, their chromosome number was 2n= 16,18,16, and their karyotype belonged to 2B, 1B, 2B,respectively. The results also indicated that the karyotype formula of the three species of Lirnoniurn as follows ： L. bicolor was 2n= 2x= 16 = 14m＋ 2sm, L. latifolium was 2n= 2x= 18 =18m,L. sinuatum was 2n= 2x= 16 = 12m＋ 4sin. The asymmetry index was 56. 12%, 56. 72% ,58.47%, respectively.
